Photocatalytic Carbon Dioxide Reduction Using Nickel Complexes as Catalysts

Abstract Nickel complexes have been investigated as catalysts in visible‐light‐driven photocatalytic CO 2 reduction for a long time. In this minireview, discrete molecular Ni catalysts are described to shed light on the utility in the reaction in relevance to metalloenzymes for CO 2 fixation. In contrast to the cases of Ru catalysts, Ni catalysts for the CO 2 reduction should be of importance due to high selectivity in CO formation.
